Individuals licensed to carry a concealed firearm under the Firearm Concealed Carry Act are prohibited from carrying a firearm on, or into, any of the prohibited areas listed under Section 65 of the statute. Private property owners may also prohibit individuals from carrying a concealed firearm on, or into, property under their control.

Owners of any statutorily prohibited area or private property, excluding residences, where the owner prohibits the carrying of firearms must clearly and conspicuously post the Illinois State Police approved sign, in accordance with 430 ILCS 66/1, at the entrance of the building, premises or real property:

H.B. 183, Section 65 (Prohibited Areas) (d) Signs stating that the carrying of firearms is prohibited shall be clearly and conspicuously posted at the entrance of a building, premises, or real property specified in this Section as a prohibited area, unless the building or premises is a private residence. Signs shall be of a uniform design as established by the Department and shall be 4 inches by 6 inches in size. … Please refer to Section 65 (Prohibited Areas) for more information on statutory regulatory requirements for signage as well as where concealed weapons are prohibited.

Pursuant to Section 65(d) of the Firearms Concealed Carry Act, signs must be of a uniform design and the Illinois State Police is responsible for adopting rules for standardized signs. The Illinois State Police has proposed rules that require a white background; no text (except the reference to the Illinois Code 430 ILCS 66/1) or marking within the 1-inch area surrounding the graphic design; a depiction of a handgun in black ink with a circle around and diagonal slash across the firearm in red ink; and that the image be 4 inches in diameter. The sign in its entirety will measure 4 inches by 6 inches.

The Illinois State Police’s proposed administrative rules allow the design and posting of a larger sign if the property owner believes the entrance of the building, premises or real property requires it. The administrative rules proposed by the Illinois State Police would also permit a larger sign to include additional language. These administrative rules have been filed with the Illinois Secretary of State pursuant to the Illinois Administrative Procedure Act.
